CD4572UBMT Equivalent & Substitute Parts

Part Overview

The CD4572UBMT is a CMOS hex gate logic integrated circuit manufactured by Texas Instruments, configured as a NOR/NAND/INVERT gate with 6 circuits and 8 total inputs (1, 1, 2, 2, 1, 1). This device operates across a wide supply voltage range of 3V to 18V and is housed in a 16-SOIC surface mount package. The CD4572UBMT is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Suitable alternatives must maintain identical logic configuration, pin compatibility, and electrical performance within the 4000B CMOS logic family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD4572UBMT are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Logic configuration: NOR/NAND/INVERT gate with 6 circuits and 8 inputs (1, 1, 2, 2, 1, 1)
• Package type: 16-SOIC surface mount with identical 0.154" (3.90mm) width
• Supply voltage range: 3V to 18V operation
• Operating temperature range: -55°C to 125°C
• Series family: 4000B CMOS logic
• Pin compatibility and functional equivalence

The onsemi MC14572UBDG and MC14572UBDR2G variants meet all substitution criteria. Both parts share identical logic configuration, package specifications, and electrical operating parameters. The primary difference between these substitutes is packaging format: MC14572UBDG is supplied in tube packaging, while MC14572UBDR2G is supplied in tape and reel format. Both are active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Both MC14572UBDG and MC14572UBDR2G are qualified substitutes for the obsolete CD4572UBMT. Selection between these two onsemi alternatives depends on procurement and assembly requirements:

MC14572UBDG (Tube Packaging): Select this variant for lower-volume applications or when tube packaging aligns with existing assembly processes. Current inventory availability is 1640 pieces.

MC14572UBDR2G (Tape & Reel Packaging): Select this variant for high-volume production runs or when tape and reel format is required for automated pick-and-place assembly. Current inventory availability is 2333 pieces.

Both substitutes maintain active product status with full RoHS3 compliance and REACH unaffected certification. The onsemi MC14572 base product number represents a direct functional equivalent within the 4000B CMOS logic family, ensuring pin-for-pin compatibility and identical logic configuration with the original Texas Instruments CD4572UBMT.

Frequently Asked Questions (FAQ)

Q: Are MC14572UBDG and MC14572UBDR2G pin-for-pin compatible with CD4572UBMT?

A: Yes. Both onsemi substitutes maintain identical 16-SOIC package pinout and logic configuration (6 circuits, 8 inputs with 1, 1, 2, 2, 1, 1 distribution). Direct board-level substitution is supported without circuit modification.

Q: What is the difference between MC14572UBDG and MC14572UBDR2G?

A: The functional and electrical specifications are identical. The difference is packaging format: MC14572UBDG is supplied in tube packaging, while MC14572UBDR2G is supplied in tape and reel format. Selection depends on assembly process requirements and volume needs.

Q: Can I use these substitutes in applications originally designed for CD4572UBMT?

A: Yes. Both MC14572 variants operate within the same supply voltage range (3V to 18V), temperature range (-55°C to 125°C), and maintain the same logic family (4000B CMOS). Functional equivalence is confirmed across all critical parameters.

Q: What compliance certifications do the substitute parts carry?

A: Both MC14572UBDG and MC14572UBDR2G are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original CD4572UBMT.

Q: Why is the CD4572UBMT listed as obsolete?

A: The CD4572UBMT is an obsolete product from Texas Instruments. The onsemi MC14572 series provides active, current-production equivalents that maintain full functional and mechanical compatibility for ongoing applications.
